Oil light?

Hello, my oil light comes on now. I checked the level it is fine. It only comes on at idle when warm. I did a search and found tons of the same problem. I don't think it is a pressure problem as the engine runs great and no knocks ticks or anything. I am going to replace the sensor above the filter but need some info on how to remove it. I can't see it clearly because of the mount.
How does the wire connect to the sensor? What type of sealant to use on new sensor? How tight? Car is 97 Deville with 130K. Thank-you, Nick

Re: Oil light?

I Would Say Sensor Also. Usually See A Red Ring In The New Sensors Threads. That's The Sealant. Draw It Up Snug & Give A Extra Few More Tightening Turns. Idling Too Low Could Do This Too. Click It Up Into Neutral & See If It Goes Out. If It Does Increase Idle A Bit

Re: Oil light?

The Wire Should Just Push On To The Tip Of The Sensor. If You Can Get A Oil Sensor Socket On It, Try That With A Extension & Rachet. They Sell Them At The Auto Store. Pliers Or Channel Locks, Which Ever You Can Reach It With

Re: Oil light?

Thank-you. I ordered it yesterday and I am going to pick it up today. $9.10. I am going to remove the filter first to let the line drain first. The connection is just push/pull? I wonder if it loosened up a little over the years and needs to be cleaned. Thank-you for your help. Nick

Re: Oil light?

Hello, I just wanted to say thank-you for the assistance. I replaced the sender 3 days ago. No more light. Once I got it out I noticed oil in the connection side. The diaphram/seal let loose. Hopefully this is the fix for a small oil leak I had. Nick
